Weldnpower high idle rpm?

[Winmac]

Hello all,
when i first got this machine i sensed that it was not up to speed, not having a tach I raised the rpm so 110v output was 60hz with the output control at 10. the diffrence in weld strike/stability was night and day. Now i have a proper tach and would like to set it by the book, it currently set at 3450rpm the owners manual im308 dose not state the high rpm, the welder is rated at 100% duty @3700rpm. , the engine is rated for 3600rpm it'is a16hp briggs welder k-1292-cv, i'm not sure what to set it at.
anyone have the oem rpm spec?

I never have used a tach on mine, but a friend just got a handheld wireless tach you just point at the shaft, so we'll probably do that soon.
Mine on High Idle is ready to go, turns the grinder pretty well. I usually use the switch down/auto setting and when I strike the rod it pops up from a very slow idle to speed. I figure it is aok because the rod burns well.

Send in a few pics of yours for fun, and I'm sure someone will come along and help you set it zactlee on:)

Set it at the 100% duty rating 3700rpm no load. Governor droop will let engine speed drop under load. If rpm drops too much under load, the governor spring should be replaced and a weak spring could be the cause of the low rpm to begin with.

To confirm the 3700rpm no load speed, auxiliary power output frequency will be 61.7Hz.

Thank you,
what is considerd acceptable droop, no load- full load, 100rpm? The machine handles load well enough but i might as well check it.
i,ve been running a ln-25 of the machine in cv, does cv operation require more power than cc feels like the machine is working harder at least.
I may snap some photos on the weekand but its just a average machine, i did replace the oem spark arrester with a real silencer, i strongly recomend this mod to any one.

Well here it is, when i got it was just a skid mount and added the axle and hitch just to make it easier to move it around the yard. ive since replaced the carb, starter drive and the awfull mushroom muffler.
After raising the rpm to 3700 ive noticed that rods burn much hotter at previous settings perhaps 20-30 amps more and i was having issues with the wire feeder noodling, seems much better now.
